    KERBDRAIN from ACO Polycrete Meets Singapore’s PUB Approval

    ACO Polycrete

    ACO Polycrete  offers KERBDRAIN inlet systems designed to channel large volumes of surface water from kerbs into the stormwater drain.  

    The road surface on Henderson Road adjacent to Telok Blangah Road, just minutes from Singapore’s bustling CBD was originally drained with  stormwater systems consisting of grated side inlet pits. These structures were connected to the city’s stormwater drainage systems by culverts.  

    Heavy rainfall during storms combined with long, steep road gradients on Henderson Road meant that large volumes of surface water would often bypass the inlet grates and cause flooding to a property downstream.  

    The Public Utility Board (PUB), Singapore’s national water agency manages the island state’s water supply, catchment and drainage works.  

    During the consultation period, PUB trialled ACO’s KERBDRAIN inlet systems as a potential solution to the flooding problem. The installation was project managed by Smitech Engineering Pte Ltd and ACO provided site support to the nominated subcontractor during the installation.  

    Finally, testing of the system prior to the handover was done with a water truck discharging water into the drain from the upstream end of Henderson Road.  

    During the evaluation, the performance of KERBDRAIN was assessed and approved by representatives of PUB. Following this success, KERBDRAIN is now being used in Singapore as a solution for problem areas where localised ponding is prevalent.  

    Unlike conventional side inlet systems, KERBDRAIN transforms kerbs into continuous inlet structures with minimal excavation. Manufactured from durable polymer concrete, KERBDRAIN consists of 500mm long pre-cast modular units each comprising an integrally cast channel and batter with inlets for continuous drainage.  

    The underlying channel then transfers the captured flow to the stormwater drain, often eliminating the need for multiple pits.

    ACO’s KERBDRAIN has been used exclusively throughout Europe, the UK, the US and Australia as a continuous lateral collection drainage solution.  

    The inlet systems keep water away from traffic lanes by effectively reducing the width of gutter flow. This provides an efficient water management solution to roads with steep gradients and flat cross flows typical of some intersections, roundabouts and a wide range of kerb line applications with depth restrictions.
